The x coordinate ,
Do what you ALREADY KNOW HOW to do...






-----------That is one of them. Now can you find y?



-
y=-19

That's the correct start...now multiply both sides of each by two and get
x+8 = 4 and y+5 = -14
x = -4 and y = -19
The other endpoint is (-4, -19).

.
. Multiply each side by 2.
. Subtract 8 from both sides

.
The x value is -4.
.



.
The y value is -19.
